Mitch tuned one of those Hyundai V8's for Rhys Millen's Pikes Peak car, and said it was a real jewel of a motor. Don't know if it was the full 5.0l version or perhaps a bit smaller. Here's a vid:

I'd buy that Genesis over a Toyota/Lexus product, simply because of the styling.
Toyota's engineering and quality are second to none, but at the end of the day they're building nothing but fugly cars now, and who wants to buy a car that's so ugly it hurts to look at it?
The Genesis is a blatant bimmer knock off, but then so is the latest Buick. Both look great, and certainly much better than anything coming out of Toyota's styling studio.
